Description of the Related Art Since feces well reflect the physiological or pathological state of a living body, it is often used as a sample for non-invasive examination of the physiological or pathological state of a living body. As described above, stool is an excellent sample, but since it may have an odor or leak to the surrounding environment, its handling is complicated and requires caution. When using feces as a specimen, the collected feces are usually suspended in a test solution and the filtered liquid is used. In this case, what is important is the quantitativeness of the collected feces. If the amount of suspended feces in the test liquid exceeds a certain range and is too large or too small, a good test cannot be performed.

ある。As a technique aiming at ensuring the quantification of such a collected sample, a conventional technique, for example, Showa 64
There is one disclosed in Japanese Utility Model Publication No. 42454. The fecal collection container disclosed in Japanese Utility Model Publication No. 42454 of 1988 has a container body capable of containing a liquid for suspending feces and at least a notch, a recess, or a through hole near the tip. A cap having a collection rod having one and connectable to the container body via a sealable means; and a drip part having a filter inside, the cap, a separation wall dividing the inside of the container into at least two chambers,
And a stocker portion formed with a sampling rod penetrating the separation wall, and the excess sample adhering to the periphery of the sampling rod penetrating the separation wall is scraped by the separation wall and stored in the stocker portion. Therefore, the amount of the sample suspended in the test solution is limited to the amount accommodated in the notch, the recess, or the through hole, and the quantitativeness of the sample is ensured.

First, since a cap is used and it is necessary to form a sealing structure for the specimen between the large-diameter container body and the cap, it is necessary to make the sealing structure between the container body and the cap highly accurate. The manufacturing of the container is complicated, and the specimen sticking to the side of the collecting rod is scraped off by penetrating the separating wall, but the specimen sticking to the tip of the collecting rod is separated from the separating wall. Since it is not scraped off depending on the sample, the sample remains suspended in the test solution together with the sample contained in the notch, recess, or through hole, and the problem remains that the quantitative property of the sample cannot be ensured.

The above-mentioned sample collection container 1 is easy to handle feces as a sample, has a simple structure, can prevent stools from leaking to the surrounding environment, and ensures the quantitativeness of the sample. However, since the container body 6 is closed by the inner stopper 13, a container body 6 whose internal volume is not so large with respect to the outer shape of the sample collecting rod 14 is used. In this case, when the sample-collecting rod 14 that has collected the sample is inserted into the inner stopper and reset, the inside of the container body 6 may have a positive pressure, and the inspector may use the outlet 7 of the nozzle portion 3 for inspection. When opening the
The sample suspension in the container body 6 may be pushed out by positive pressure, jump out, and be scattered around. Further, when the collected sample is liquid stool, the positive pressure generated when the sample collecting rod is inserted exerts a force to push the sample back out of the container body 6, and the collected amount varies. May occur.

Since air is continuously discharged through the communicating outer groove, through hole, and inner groove, the air inside the container body is not compressed and the inside of the container body does not become a positive pressure. Therefore, the suspension liquid is scattered during opening. Can be prevented, and the sample is not pushed back.
